So I was thinkin instead of making a 48x48x24 indoor tank, why not throw them out for summer? Something like a 8x3x3 maybe. Maybe even 10x3x3. So if I did build this, it would be 2 feet under and 1 foot above ground to keep all the crap out and varmints. I live in IL so it wont be 100 degree summers, we usually peak 95 for a few days. It wont be in sunlight until noonish, and will come out of it around 4-430pm. The main question is, is 2 feet under ground good enough to keep it under 80, or would 3 feet under 1 foot over be a better situation?
